It is the framework that consists of software components that are reusable and enables content that is interactive over the Internet. : Performance management in component-oriented systems using a model driven architecture approach. If the calling application is not an ActiveX component, this value can be set to NULL. Componentslink. distributed object technologies embody a non-traditional architectural model. With the growth of the software size and complexity, the traditional approach of building software from scratch, becomes more and more inefficient in terms of productivity and cost. It is a scaled-down version and is built with all the essential details of the system. Component Object Model. Uses dynamic loading to eliminate frequent code client re-compilation. Without a commonly agreed upon software component object model, Web applications will suffer from the same architecture incompatibilities which separate CORBA and COM+. The three major component models that are used successfully today are: COM. The Component Object Model (COM) is a component software architecture that allows applications and systems to be built from components supplied by different software vendors. Distributed Object technologies are best typified by the Object Management Group's Common Object Request Broker Architecture (CORBA) , and Microsoft's Distributed Component Object Model (DCOM) [Microsoft 1998]. 2 Component Object Model (COM)and Distributed COM (DCOM) Introduced in 1993, Component Object Model (COM). CORBA services: CORBA Object location service - CORBA messaging service - CORBA Event Se rvice -CORBA Security Service - CORBA Object Transaction Service. The infrastructure for COM now is part of the operating system and using this model for sharing components (“sharing implementation”) is accepted practice. Each aspect of ArcGIS Server plays a role in managing GIS functionality and data and making that functionality useful to end users. The Component Object Model (COM) is a system within Windows to enable interaction between software components through the operating system. So what this means for many users of middleware is that a component based architecture will really only help a lot with flexibility in terms of creating new game objects, or modifying old ones. It provides four essential views − The logical view or conceptual view − It describes the object model of the design. COM is the basic architecture of the simulation, and ActiveX is the defined object model built on top of that architecture, said Johnson.
